Bringing my car in a few days to lethal racing. I've checked all over Texas and Louisiana and these guys sounded the best hands down. I work a 14 and 14 schedule they offered to do it when I go to work car will sleep inside. It will only take 4 to 5 days for upgrades. Once again they offered to do it when I'm gone come in ready to go. That means a lot to me. Can't wait then I will add the supercharger.
